摘要:
A circuit for amplifying a display signal transmitted to a repair line by using a non-inverting amplifier is disclosed, which comprises a voltage follower, a non-inverting amplifier, a repair line, a thin film transistor (TFT) and a liquid crystal (LC) capacitor. The voltage follower is electrically connected to a data driver chip to thereby provide a display signal to the non-inverting amplifier. The non-inverting amplifier amplifies the display signal to thus obtain an amplified display signal, and transmits the amplified display signal to the TFT and the LC capacitor through the repair line. The amplified display signal is kept at a desired voltage level when the LC capacitor receives the amplified display signal.
摘要:
A digital-to-analog conversion unit, and a driving apparatus and a panel display apparatus using the same are provided. A driving voltage output from the digital-to-analog conversion unit can be a positive polarity voltage or a negative polarity voltage, wherein the driving voltage output from an output buffer is a positive polarity voltage and the driving voltage output from an output inverter is a negative polarity voltage. The apparatus only needs one set of grayscale voltage so that the layout area of the apparatus, and the flicker and the residual images of the display panel can be reduced.
